1) State the equilibrium expression/equation for the provided reaction: A) + 3 B) = +3D) [K2] 2) 2.44 mol of gaseous hydrogen bromide is added to an empty 3.16 L container. When values are no longer changing, at 62.5 °C,0.55 mol hydrogen gas is collected. Using the provided skeletal equation, determine the value of the equilibrium constant, at 62.5 °C, to 2 decimal places. HB = Brale) + H21) [K5] 3) With regards to the provided equilibrium system, discuss the effect of each of the indicated disturbances to an equilibrium system. [C5) 21,0 (8) 4 NO28) +0,6) + 333 kJ a) the temperature of the equilibrium system is decreased b) a functional catalyst is added to the system at equilibrium c) the pressure acting on the equilibrium system is increased d) some NO2(aq) is added to the system at equilibrium e) some N2O3(aq) is added to the system at equilibrium 4) At a certain temperature, the provided system has a Keq of 4.871x10? Determine the equilibrium concentration of the carbonate ion, at this temperature, when 0.038 mol of bicarbonate ions, HCO,', is added to an empty 2.0 L reaction vessel. Answer in scientific notation, with two decimal places; clearly show your work. [17] HCO3) =co ) + Hà) Map 1+ ( 5) What mass of lead(II) bromide, PbBr2, (rounded to 100 of a gram) can be dissolved to create a 4.00 L solution at SATP?
